![]() A non-technical assessment to a commercial-scale CO2 storage facility in central Utah was conducted. Area of Review Delineation and Risk Asse ssment on the Navajo, associated seals and shallow groundwater aquifers identified the most significant risks and mitigation options. CO2 capacity estimates for the Navajo Sandston e approximately 18 kilometers from the Hunter plant are well in excess of the 50 million tonnes goal of the project. A comprehensive analysis of the reservoir a nd seals was conducted, providing data to the model, simulation and risk assessment groups on the proje ct. As a result, potential injection sites were moved stru cturally down-dip (to the west), into the high permea bility (~200 mD) and high porosity (20%) Navajo san dstone. However, petrophysical logs fr om wells near Hunter indicate porosity of only 2-4%. Initial geologic c haracterization efforts focused on sites immediately adjacent to the Hunter plant, including the deep eolia n Permian White Rim Sandstone, which in outcrop a nd core from other locations indicates high permeabi lity and high porosity. A high-level technical sub-ba sinal evaluation was performed on the area surround ing the Hunter and Huntington power plants to verify CO2 storage capacity and integrity. ![]() Transportation and intermediate compre ssion would increase the per tonne costs, but will be highly dependent on specific injection locations and available rights-of-way. Amine -based and cryogenic-based capture assessments w ere performed for approximately 3 million tonnes per year for one of the boiler units at the Hunter plant, yi elding cost of capture estimates of $56/tonne and $4 1.50/tonne. The Hunter plant was chosen because o f an interest in CO2 capture technology by the plant operator, Rocky Mountain Power, and also because i t is a representative example of a typical coal-fired g enerating station in the Rocky Mountain west. ![]() The nea rby Huntington power plant, also operated by Rocky Mountain Power, was evaluated as a secondary sou rce of CO2. The Rock y Mountain CarbonSAFE team identified the Hunter Power Plant in central Utah as the primary source of CO2 on which this more » study would be focused. The a ssembled project team consisted of academic, indus try and governmental agencies covering the technic al and non- technical challenges of a commercial-sc ale CO2 storage facility capable of storing 50 million tonnes of anthropogenically-sourced CO2. of Technology (Netherlands) Sponsoring Org.: National Energy Technology Laboratory (NETL) OSTI Identifier: 1779820 DOE Contract Number: FE0025912 Resource Type: Technical Report Country of Publication: United States Language: English Subject: 54 ENVIRONMENTAL = ,Īn integrated CCS pre-feasibility study, CarbonSAF E Rocky Mountain Phase I, was conducted by the U niversity of Utah and its partners as part of the US D epartment of Energy’s Carbon Storage Assurance a nd Facility Enterprise (CarbonSAFE) program. of Technology, Stockholm (Sweden) Delft Univ.
